Hi,

I just have a really quick question about Case / ATI 5850 Cooling. I'm running completely stock with a salvaged old dell dimension micro ATX case, which I couldn't bare to through out.
Although I have modded the fan options in MSI afterburner, the Graphics card does needs 100% fan usage to keep a constant stable temperature when gaming, otherwise it would rocket.
I'm getting abit cheesed with it running like this as its bloody loud. I don't want to spend too much money to sort this inconvenience either. I was thinking about maybe making a whole in the side of the case and fixing some sort of fan to it just above the exhaust slats, which are near where you screw the card down. Not sure whats best so I thought I'd ask the experts on these matters. If it's another fan I need can you be specific about the size/type its just I recently brought a 92MM for the front intake recently. It's not PWM or anything and just runs full throttle the whole time. Its quite but doesn't shift hardly any cubes.

Cheers

I would mount the fan lower and more towards the center so that it is blowing fresh air towards where the turbine style intake fan on the card is. That way the card would be getting nice cool ~21c air instead of the warm air from inside the case.

As for fan size... probably a 120mm I wouldn't go bigger. If you want to get crazy you could use a high speed 80mm fan and create a duct to pipe the air straight to the cards intake. That would be a little more work but would probably pay off.

Personally I would just put a 120 in the side panel and be done with it. You could also try to find a used aftermarket heat sink for it.
